As a highly efficient evaporation and concentration equipment, multiple-effect evaporator is widely used in chemical, food, pharmaceutical and other fields. Its working principle is to achieve continuous evaporation and concentration of materials by repeatedly utilizing heat energy.
However, how to accurately measure the liquid level in the multiple-effect evaporator is the key to improving the stability of the production process and product quality. In this regard, guided wave radar level meter has become an ideal choice with its excellent performance and unique advantages.
Guided wave radar level meter is a measuring instrument based on the time travel principle. It measures the liquid level by emitting microwave signals and receiving the signals reflected from the surface of the medium.
In the application of multiple-effect evaporators, due to the different stages of evaporation, the physical properties of the liquid, such as density, viscosity, and temperature, will change, which brings challenges to the liquid level measurement.
Traditional level measurement methods such as differential pressure and float types often seem to be unable to cope with these changes, while guided wave radar level meters can adapt to these changes and provide stable and reliable measurement results.
The probe or cable of the guided wave radar level meter is in direct contact with the measured medium, which can effectively avoid measurement errors caused by factors such as steam and foam. Secondly, since the propagation of microwave signals is not affected by changes in the electrical constant and density of the medium, high-precision measurements can be maintained even when the medium characteristics in the multiple-effect evaporator change.
In addition, the guided wave radar level meter also has a self-cleaning function, and its probe design can reduce material adhesion and ensure long-term stable operation. In practical applications, the installation of the guided wave radar level meter is also relatively simple. Because it adopts a top-mounted method, there is no need for complex construction inside the container, which greatly simplifies the installation process and reduces maintenance costs.
At the same time, modern guided wave radar level meters are usually equipped with intelligent communication interfaces, which can easily access the factory’s automation control system to achieve remote monitoring and data analysis.
Guided wave radar level meter also shows its unique advantages in energy conservation and emission reduction. Through the precise control of the liquid level of the multiple-effect evaporator, the evaporation process can be optimized, energy consumption can be reduced, and operating costs can be reduced.
At the same time, accurate liquid level measurement can also help improve product quality and reduce material waste, which is of great significance to enhancing the market competitiveness of enterprises.
